Well there you go, 60% for me, thats me being extremely narcissitic and they wont award me any marks even for partial solutions.

Come on Scaling, work your magic, put me to a Band E3 !!

 

[midifile]

Im thinking between 78 and 80 after seeing the answers. What would that scale to ??

I'd say 98-99

I cant imagine that many people getting above 80/84 and it was a hard test so hopefully it will align well

 

[u-borat]

pretty sure i got 77 after seeing these solutions.

 

[Lanser7]

damn. i only got 81/84 (lost 2 marks for stupid mistakes in 6. c) i)

 

[himiniji]

I'm going to be honest, I don't remember what I put for everything, but I think I got ~81-83. So stoked! What would that scale to?

[hodarrenkm]

Isnt the answer to 4)b)ii) 7! not 8!/2!

it is 8!/2 cos john either goes in front of or after Barbara

 

[Etude]
